OpenShift installation
Preparation
Centos 系统，kernel 版本不能太低, 否则需要升级一下kernel, 下面是我升级的版本,
# cat /etc/redhat-release
CentOS Linux release 7.0.1406 (Core)
# uname -a
Linux i-lwfsocpz 4.16.6-1.el7.elrepo.x86_64 #1 SMP Sun Apr 29 16:50:56 EDT 2018 x86_64 x86_64 x86_64 GNU/Linux
升级执行如下,
官方源： http://elrepo.reloumirrors.net/kernel/el7/x86_64/RPMS/
# yum install -y http://elrepo.reloumirrors.net/kernel/el7/x86_64/RPMS/kernel-ml-4.16.6-1.el7.elrepo.x86_64.rpm
# rmp -qa | grep kernel
# rpm -e kernel-3.10.0-123.el7.x86_64
# vi /etc/default/grub
修改成 GRUB_DEFAULT=0
# grub2-mkconfig -o /boot/grub2/grub.cfg //重新编译内核启动文件，以后升级完内核也要执行一次
Installation
Modify docker conf
vi /etc/sysconfig/docker, append the following line:
INSECURE_REGISTRY='--insecure-registry 172.30.0.0/16'
Account: developer/developer
failed: iptables: Bad rule (does a matching rule exist in that chain?)
# systemctl stop firewalld -> restart docker
When firewalld is started or restarted it will remove the DOCKER chain from iptables, preventing Docker from working properly.
# setenforce 0
# tar -zxvf openshift-origin-server-v3.9.0-linux.tar.gz
# cd openshift-origin-server-v3.9.0-191fece-linux-64bit/
# cp k* o* /usr/local/bin/
# openshift start & (always throw error)
Run in the container:
(edit /etc/hosts, add master.example.com map 10.35.0.2, default is 127.0.0.1, 登录时老跳到127认证，出错)
# oc cluster up --public-hostname=master.example.com
Using nsenter mounter for OpenShift volumes
Using 127.0.0.1 as the server IP
Starting OpenShift using openshift/origin:v3.9.0 ...
OpenShift server started.
The server is accessible via web console at:
